about Advantech PCI-1757UP driver...

  Hello  all,
            Im new to this list.
   I want to buy a simple PCI I/O card with Linux source code....
So i found Advantech's  model is simple...
but, they said they won't provide any linux driver source code...

but, when i download "comedi-0.7.60" tar file from comedi site...
in this "drivers" directory... i saw a file "pci1757.c"
in which there is a line "Support card:Advantech card pci1757up"..
So is this "comedi-0.7.60" supports.. Advantech PCI-1757UP ..

but, in latest one of "comedi-0.7.68" ... about  Advantech PCI-1757UP...it has not given....

         Please can anybody give suggestion.. that whether this comedi  provides Linux driver for "Advantech PCI-1757UP card"????????

                                          Regards
